fall out of the lock and be lost and cannot be pushed out of the lock to permit insertion of another key at the other side of the lock or to permit the lock to be picked.

A further object is to provide a device of this character comprising a notchedplate pivotally mounted relative to the lock plate and adapted to partially close the key hole wherebythe notched portion may be selectively positioned in or out of registration with the key hole of the lock.

A further object is to provide a device of this character comprising a retaining plate pivoted to a lock face plate and operable by means of a pivoted arm adapted to be locked in desired position relative to the face plate to hold said retaining plate against movement.

\Vith the above and other objects in view, the invention resides in the combination and arrangement of parts as hereinafter set forth, shown in the drawing, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawing: v Figure 1 is a View in front elevation of a door lock face plate having my device attached thereto. a Figure 2 is a fragmentary plan view in front elevation showing my device appliedv to the door lock face plate inlocking position. I

on line 3-3 of Figure 1.

Figure 1 is a fragmentary vertical sectional view showing the retaining plate opcrating lever in released position.

Figure 5 is a perspective view of ing plate.

Referring to the drawing, which illustrates the preferred embodiment of the invention,

my retainthe numeral 10 designates a conventional 1 31. Serial 1%.- sarese.

door lock face plate having a key hole 11 and carrying a knob 12. In spaced relation below thekey hole 11 an opening 13 is formed in the face plate 10, andthrough this opening 13 projects a stud 14 carried by a sub stantially fan-shaped retaining plate 15 whose upper edge is preferably curved in an arc concentric with opening 13. The upper edge of the retaining plate is provided at its center with anotch 16 ofv a shape conforming to'the shape of the lower portion ofthe key hole 11 with which it is adapted to register. A ring 17 engages the face. plate 10'and encircles the opening 13. An arm 18- is pivoted at 19 on the outer end'of stud 14, and is provided with a cam-shaped nose 201adapted=to bear against the ring 17.

My device is applied to the inner door lock face p'late'whereby the arm 18 projects from the inner side of thedoor. When it'is de-. sired to'lock the door from the inside the key (notshown) is actuated to setthedoor'lock I '(not shown) and the plate15 is positioned with the -notch 16' out of registration with the key hole whereby the lower portion ofthe 7 keyhole is closed by the 'plate', thus preventing removal of the key from the lock. The arm 18 is then depressed intoengagement with the lock face plate to force the cam nose '20 against the ring 17 and to draw the stud the ring 17 whereby movement from locked position is resisted. When the retaining plate Figure 3 is a vertical sectional view taken has been so positioned the'key may not be withdrawn from the lock nor pushed out of the look from the outside to permit insertion from being picked; It will also be seen that me j - the retaining plate will serve to retain the key in'the lock at all times when positioned as shown inFigure 2 whether the door is, locked or not, and the key cannot fall from the lock and be lost in the opening and closing of the door.

The invention having been set forth, what is clai ned as new and usefuil H I A v V 1.
